Smoke-condenser.



PATRICK MCDERMOTT, OF POTOMAG, MONTANA.

SMOKE-CONDENSER.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed September 5. 1906. Serial No. 333,397.

To all whom it may concern:

Be it known that I, PATRICK MCDERMOTT, a citizen of the United States ofAmerica, and a resident of P0- tomac, in the county of Missoula andState of Montana, have invented certain new and useful lmprovements inSmoke-Condensers, of which the following is a specification. I

This invention relates to smoke condensers, and one of the principalobjects or the same is to provide means for increasing the draft andcarrying away the smoke from the furnace of a smelter or other plantwhere it is desired to get rid of the smoke and keep it outoi the air.

Another object of the invention is to provide a con- 4 denser attachedto the outlet of a smoke duct or flue consisting of a water pipedisposed at an angle to the outlet so as to convey the smoke by a streamof water from the outlet to the ground.

These and other objects may be attained by means oi the constructionillustrated in the accompanying drawing, in which the figure is a sideelevation of a smoke condenser made in accordance with my invention.

Referring to the drawing for a more particular description of myinvention, the numeral '1 designates a smoke duct or flue, and securedto its outlet end is a three-way tubular connection 2 provided with aninclined member 3 to which is connected a discharge pipe 4 at its lowerend, while its upper end 5 is open to receive a conical water dischargenozzle 6. The nozzle 6 is connected to a tapering pipe section 7 bymeans of a set screw 8. said pipe section 7 being connected to a pipe 9,the upper end of which is attached to a wooden elbow member 10, theupper portion 11 of which may be openat the upper side and connected atits upper end to a trough 12 to which water is supplied from anysuitable source.

The operation of my invention may be described as follows: Water fromthe trough 12 flows through the elbow 1.0, .11, into the pipe 9, andthrough said pipe to the tapering member 7 and through the nozzle 6, andas the smoke emerges from the outlet in the flue l,

the water intersecting the smoke will carry it out through the dischargepipe 4 and onto the ground. Owing to the force of water the draft of theflue 1 is increased, and the smoke is condensed and carried to theground, thus preventing the same lrom filling the air around the plant.

From the foregoing it will be obvious that a smoke condenser made inaccordance with my invention is of simple construction, can be quicklyconnected to the smoke duct of a smelter or similar plant, and willoperate efiiciently to prevent smoke from rising and at the same timeincrease the draft of the furnace.

Having thus described the invention, what I claim is:

1. A smoke condenser comprising a three-way connection attached to thesmoke outlet of a flue or smoke duct and provided with an inclinedmember extending at an angle to the smoke outlet, a nozzle inserted insaid inclined member and connected to a water pipe, a trough connectedto the upper end of said pipe, and a discharge pipe connected to ,thelower end of said three-Way connection, substantially as described.

2. A smoke condenser comprising a three-way connection attached to theoutlet end of a smoke flue, a discharge pipe connected to one end ofsaid connection, a water discharge nozzle connected to the opposite endof said con nection, and the outlet end of said nozzle being disposed inline with the smoke outlet, and means for discharging Water through saidnozzle, substantially as described.
